Post Project 19: Bury the Hatchet, Unbury the Axe (3)

In the course of this article series [1] we first showed how
to program a PICAXE chip and how to build basic input and
output circuits (Elektor.POST Project No. 8). In the second
installment (Elektor.POST Project No. 16) we covered the
control of various types of switches, and how to calculate
the appropriate component values for your designs. This time we will be
looking at how to read and process values from analog inputs, describing
multiple output types using circuits connected to a pulsewidth modulation
(PWM) output, in combination with the already available PICAXE commands.
We will also be able to position mechanical parts accurately using
servos controlled by a PICAXE chip, as well as creating and playing monophonic
ringtones!
